After adding my device ID (0x67781002) to the plist.info files inside the following kexts:

/S/L/E/AMD7000Controller.kext

/S/L/E/AMDRadeonX4000.kext

I rebuilt the permissions, rebuilt the cache and restarted the OS. The graphics card is showing up in the system information but the display isn't working. Only the VMWARE SVGA is showing in Preferences/Display properties
